Which of the following statements concerning solubility is/are CORRECT?
1) Ionic compounds composed of Group 1A metal ions and halide ions,such as NaCl,are insoluble in nonpolar solvents.
2) The solubility of the halogens (Cl₂,Br₂,and I₂) in polar solvents is greater than their solubility in nonpolar solvents.
3) The solubility of polar molecules,such as sugar,in polar solvents is generally greater than their solubility in nonpolar solvents.

Question

Quizplus · Accepted Answer

Statement 1 is correct because ionic compounds composed of Group 1A metal ions and halide ions are highly polar and require a polar solvent such as water for dissolution.
Statement 2 is also correct because halogens are highly polar and have a large dipole moment. Therefore, they dissolve well in polar solvents.
Statement 3 is correct because polar molecules dissolve well in polar solvents due to their similar intermolecular forces. Sugars are highly polar molecules and dissolve well in water, a polar solvent.
